Simon is primarily an exponent of line the quality of which his commissioners have described as spontaneous, energetic, quirky, inherently humorous, adaptable and elegant. One enthusiastic USA Art Director said“Spilsbury’s drawings always jump off the page and bite me on the ass.”

Over the past 20 years his work has appeared in many advertising campaigns, TV programmes/idents and column inches across the globe, including Nike, Virgin, Cobra Beer, C4, Vodafone, Paramount Comedy Channel, The London Election, Martell, Waterstones, Luerzers Archive, The Sunday Times and The Guardian.

His work has also won numerous awards including British Illustration Gold, D&AD Silver, Communication Arts, Print Magazine and American Illustration.

His work has featured in Luerzers 200 Best Illustrators and Taschen’s 100 Illustrators, where the mercurial Steve Heller wrote “Spilsbury’s expressive and chaotic line is a high-speed engine that pulls his drawings along at a frenetic pace.”
